RMC’s planning and design professionals understand complex wastewater treatment and permitting issues and identify project alternatives that provide the greatest increase in reliability within available project funding.

Wastewater Treatment Facilities

Novato Sanitary District

The Novato Sanitary District is upgrading its wastewater treatment facilities to increase treatment reliability, improve compliance with regulations, replace aging infrastructure, and accommodate a 7:1 wet weather flow without bypassing. For this $84-million project, the RMC team:

• Completed predesign, preparation of CEQA documents, and funding analyses
• Designed extensive modifications and upgrades to the existing treatment plant, including systems for UV disinfection, odor control, and SCADA control
• Designed program for phased construction so the plant could continue to operate
• Provided engineering services during construction

 

Ultraviolet Disinfection Facility Design

City of Palo Alto

This design project was a continuation of our work with plant staff, partner agencies, and stakeholders that began with a Long Terms Goal Study and resulted in a decision to convert to UV disinfection. We:

• Completed the fast-track design of the addition of sodium hypochlorite and sodium bisulfite facilities
• Designed and provided engineering services during construction of UV facilities configured to provide simultaneous disinfection of recycled water and secondary effluent in adjacent UV channels
• Upgraded the existing dual media filters for Title 22 compliance

 

Water Pollution Control Facility Expansion

Encina Wastewater Authority

RMC works as extension of Encina Wastewater Authority (EWA) staff assisting with large project program management, upgrading the plant and remote facility asset management plans, and implementing plant upgrades from concept to design and construction. EWA provides wastewater treatment for six agencies in northern San Diego County. Our services include:

• Providing program management for the Flow Equalization Project, Building Program and Phase V Energy Management and Heat Dryer Solids Handling Facilities
• Annually updating the Comprehensive Asset Management Plan for use in planning capital rehabilitation projects
• Implementing capital improvement projects throughout the treatment plant and remote facilities

 

South Placer Regional Wastewater System Evaluation

South Placer Wastewater Authority

RMC evaluated the wastewater collection, treatment, recycling and disposal system that serves the South Placer Region. We:

• Defined project needs to maintain regulatory compliance, human health and safety, and life cycle cost efficiency
• Provided financial analysis, including rate implications for outside service areas
• Established a Capital Improvement Program for the WWTPs, prioritized for feasible implementation
• Developed plant expansion design criteria, plant layouts, rehabilitation plans, and cost estimates

Main Wastewater Treatment Plant Land Use Master Plan and EIR

East Bay Municipal Utility District

To accommodate future expansion needs, the East Bay Municipal Utilities District acquired 15.9 acres of land adjacent to its Main Wastewater Treatment Plant—located on a 48-acre site in an industrialized area of West Oakland. Finalization of a land use master plan and preparation of a programmatic environmental impact report (EIR) will guide the near-and long-term use of the property. RMC:

• Prepared a Land Use Master Plan, developing a 30-year vision for the plant and site
• Led preparation of a programmatic environmental impact report (EIR)
• Completed a Food Waste Expansion Project-level Negative Declaration
